Bachmann, the only female GOP candidate in 2012's presidential election, says in a new interview that people "aren't ready" for a female commander in chief.

"I think there was a cachet about having an African-American president because of guilt," she told columnist Cal Thomas. "People don't hold guilt for a woman."

Thomas interpreted Bachmann's comments as suggesting President Barack Obama landed in the White House because of "guilt" over slavery and civil rights struggles.

According to The Washington Post, Bachmann argued Clinton also doesn't have the benefit of being a "new and different" candidate like Obama. "Effectively, she would be Obama's third and fourth term in office," the Tea Party favorite said, calling Clinton "the godmother of Obamacare."

Sen. John McCain (R-Ariz.), however, disagreed with Bachmann's political predictions in an interview with CNN's Piers Morgan on Thursday.

"I would bet, my friend, as much as I hate to admit it, that right now - this is why we have campaigns - but right now, if the election were tomorrow, Hillary Clinton would most likely be the president of the United States," he said.

McCain said he wouldn't vote for the former secretary of state, but more females in Congress could mean voters are more open to women in office than Bachmann thinks.

Still, the latest Gallup poll appears to show her as the frontrunner for the Democratic Party ticket. Nearly three out of five Americans view her favorably while Vice President Joe Biden maintains mixed ratings, according to findings published Friday.

Bachmann told Thomas the Tea Party can stop Clinton from a successful run if they "remind people... how she has operated in the past with these types of responsibilities. She was in charge during the Benghazi debacle."

Politico reports the bipartisan section of the Senate Intelligence Committee report on Benghazi does not fault Clinton. Claims otherwise are "patently false," a rep for Correct the Record told the political news website.
